摘要

摘要: 小型氮气液化器具有经济性、便携性，可满足偏远地区或野外环境以及科研实验室的小用量液氮供应。以深冷混合工质节流制冷循环为基础构建了一种氮气液化循环，采用遗传算法结合MATLAB和ASPEN HYSYS对该循环进行优化，并开展了实验验证装置的研制和测试。实验结果表明，该氮气液化器的比功耗为1.02 kW·h/L，加上PSA制氮机，整个设备能耗为1.77 kW·h/L。同时成功研制了5～10 L/h系列微小型氮气液化器，可满足客户对不同液氮量的需求；与现有商用氮气液化器相比，该氮气液化器在比功耗、成本和可靠性等方面具有明显的优势。

Abstract: The miniature nitrogen liquefier can meet the requirements of small amount of liquid nitrogen supply in remote areas,field environment,and scientific research laboratories.A nitrogen liquefaction cycle based on low-temperature mixture refrigerator cycle was built and optimized using the genetic algorithm combined with MATLAB and ASPEN HYSYS.And an experiment device was developed and test.The experimental results show that specific power consumption of the nitrogen liquefier is 1.02 kW·h/Land considering the PSA nitrogen generator,that of the entire device is 1.77 kW·h/L.The series of miniature nitrogen liquefiers can achieve the capacity of 5~10 L/h,and can also be customized according to specific needs.Compared with the commercial nitrogen liquefiers,the liquefiers have obvious advantages of low specific power consumption,low cost and high reliability.
